Just checked out the Zone kit. The add a leafs can ride pretty rough in my experience but looks like you already have a plan for remedying that. If you change your mind and stay SUA the Hell Creek MT leafs are nice. When combined with the zone shackles I'm guessing it would be in the 4-5" range
Great. I think those seats will look awesome restored/refreshed regardless if you swap to the 97+ dash or keep it original.
